Which language should I learn for frontend development? I don't know much about it

Question

AngularJS , Node js, Bootstrap, or any other

Answer 1

html, css, JS, some bootstrap.

Answer 2

HTML, CSS, JavaScript, JQUERY

Answer 3

None of those you listed are languages. Firstly, you'll need to learn HTML, CSS, and then JavaScript. The first two are languages for building and styling webpages, collectively. The third, JavaScript, will be your first "real" programming language, and is very ubiquitous in the programming world.

After that, I'd highly recommend you at least *touch* on NodeJS (which is JavaScript, but *not* in the browser). You can then learn AngularJS if you want, but it's a little old outdated nowadays.
